Description
WriteBase. Offset added to the graphics memory base to specify where VGA write oper-
ations start. This value provides DWORD address bits [21:14] when mapping host VGA
writes to graphics memory. This allows the VGA base address to start on any 64 KB
boundary within the 8 MB of graphics memory.
Description
ReadBase. Offset added to the graphics memory base to specify where VGA read oper-
ations start. This value provides DWORD address bits [21:14] when mapping host VGA
reads to graphics memory. This allows the VGA base address to start on any 64 KB
boundary within the 8 MB of graphics memory.
Description
